Bank of America's investment banking fees edged up 4% during the second quarter despite a broader decline in advisory work that has hit rivals hard.

The Wall Street bank brought in $718m in investment banking revenue in the three months to the end of June, compared with $692m a year earlier. The gain is largely down to more than doubling fees from equity capital markets work, which jumped to $122m during the second quarter, with both M&A fees and debt advisory revenue declining.
